How do you figure out the number of neutrons in a atom? Atoms are all made up of three kinds of subatomic particles. These are electrons, which have negative charges, protons, which have positive charges, and neutrons, which are neutral. What family is carbon in? The elements are divided into nine families: Electrons in the third orbital of sulphur are involved in reactions.

How many electrons does a Sulphur has 16 electrons about its nucleus. These orbit around at different energy levels, called shells, the innermost shell being the most tightly bound to the positively charged nucleus. What is the purity of triple distilled mercury? Triple distillation is the most common refining method for mercury.

In this process, the temperature of liquid mercury is precisely controlled and raised. Some impurities evaporate first, and are All elements in Group 13 have three electrons in their outermost energy level.

The two most popular elements in this group are Boron and Aluminum. Both Boron and Aluminium have 3 valence electrons, What are the group names of the periodic table?

What are their traits? The groups of the periodic table are the vertical columns, running up and down. There are eighteen groups; each of which is given a different family name. What are the everyday uses of Hydrogen? Hydrogen is found in massive quantities all over the universe. It is found in many places right here on Earth. So, it should come as no surprise that it is used in so many of the products that we Why are Group 1 metals so reactive and what are they called?

Group 1 of the Periodic Table, or the Alkali Metals, include lithium, sodium, potassium, rubidium, caesium, and francium. The columns of the Table reflect a "family" of elements; each At what temperatures is lithium a solid, a liquid, or a gas?

The Alkali metal Lithium, third element of the Periodic Table, is a very soft, silvery metal. Please explain clearly and in detail.

Atoms are made of three different types of particles. Protons and neutrons are in the nucleus; electrons are found in outer shells, circling the nucleus. An atom of any element has a set number of The elements in the Periodic Table are arranged from left to right and top bottom based upon what There are several aspects to the organization of the periodic table of the elements.

First, all the elements are ordered, going left to right, by atomic number — which is the number of protons If you lower the temperature enough, can all the elements be turned into solids? The temperature at which various elements change phase depends on both the temperature they are at as well as the pressure they are placed under. If the pressure and temperature of any element is What 5 elements are liquid on a hot summer day 38 C? There are 5 elements that are liquid at 38 degrees Celsius.

Four of these are metals, all of which can be used in thermometers. Cesium atomic number 55 and Francium atomic number 87 are Alkali Why are the elements Bromine and Mercury liquid at room temperature? Liquids are the in-between state where Iron, as a transition metal, shares the same outer electronic configuration as the rest of the metals in its class, meaning the 4s orbitals are all the same. Only the inner 3d orbitals change Why do magnesium, phosphorus, and zinc exhibit slightly higher first ionization energies than the The 1st ionization energy, 1st ie the amount of energy needed to remove the most energetic electron, increases going bottom to top up the family and left to right across the period on the What is another term for an unreactive element?

The letters scrambled up are: I am doing a ArgonIt is called an unreactive element because it has a stable electronic configuration and does not share its electrons with other atoms. Argon, discovered in , makes up 0. Henry Cavendish, a brilliant recluse, is credited with its discovery for communicating his work in to the Royal Society in England with an inflammable gas produced by the action of acids on What is element 35?

Describe its atomic mass, configuration number, and charges. Element 35 is Bromine, an member of the halogen family Its standard atomic mass is The most stable and widespread form of Bromine has 45 neutrons, for What are the differences between calcium, tin, and aluminum? All 3 are elements.
